I occasionally give some of my watches an ultrasonic to get the grime out of nooks and crannies. Usually I strip the case down, so bracelet off, case back off, movement/dial out, bezel off if applicable and crystal out.
However, today I was wondering, is this necessary? Can I put the midcase in the ultrasonic without removing the crystal (assume 60’s plexi/hesalite) or is there a risk of the hesalite fracturing?
